Mild Weather Looks to End in Time for Thanksgiving

We have been spoiled for several weeks with temperatures well above normal for the month of November. This week, temperatures are expected to reach into the 60s, possibly a few 70s which is well above the 40-degree highs we typically see this time of year.

Monday's Forecast Highs

Looking at forecast models, some models are showing changes in the weather with an increase in precipitation and much cooler weather by the end of the upcoming weekend or the start of the next workweek.

Sunday's Forecast Highs

A large dip in the jet stream along with a low-pressure storm system looks to start impacting the state by late Sunday or the start of Monday. This system looks to bring chances of rain or even snow as cold temperatures spill into the region.

There remains many factors in this forecast due to another low-pressure system across the northwest United States and parts of southwest Canada that could affect the other storm system. Models still do not agree on the precipitation as the American (GFS) model is delaying the precipitation and forecasting less moisture but the Euro (ECMWF) is showing a different story with more precipitation and starting earlier.
